A method for operating a global shutter image sensor includes performing both a global
shutter (image capture) operation and a rolling shutter (readout) operation. During the global
shutter operation, image information (charges) are captured by photodiodes in every pixel,
and then simultaneously transferred to charge coupled gate (CCG) devices provided in each
pixel. The rolling shutter operation includes performing multiple correlated double sampling
(CDS) readout phases utilizing readout circuits that are shared by groups of pixels (eg, four …
